230 Turbo

[48mirage]

I don't usually post links to ebay, but I saw this at my mouth watered.

Since I do not have the funds to purchase this setup for myself I will gladly use my D30 as the test vehicle for this setup if one of you folks would purchase it and send it to me.

Thats gotta be a neat setup, have never seen an exhaust manifold like that, I have an industrial ex airport tug 230 that I am working on for my 41 coupe and the exhaust is the same a the normal car type, that turbo setup gives me ideas...........lol........thanks for posting it......andyd

Wow! That is too cool. I want more info (hp gain, etc).

[48mirage]

My only concern would be the rpm requirement to get this thing to work. I don't think I want my flathead trying to run at 6000 rpm.

Somebody bought it.....was it one of us?????

I find it interesting that the turbo will draw the air/fuel mixture through the carb and then compress it into the intake manifold. I've not seen many carburated / turbocharged engines, but I thought the turbo was normally pushing the air through the carb.

Would be better off running a Paxton or Procharger system. They are the same basic theory of a turbo, with the advent of a belt, same as Roots style blower systems, only better. And would not have the lag of a turbo, plus keep the RPM and Powergain to a minimal, that it would be a benifit. :]

I would bet that there wouldn't be any need to spin a flathead too tight with that setup. Don't forget that the T-bird motor was only 2.3 liters, and ours are almost 4 liters, so it should spool up quickly. I had one of those 2.3 turbo motors in a Merkur, and it would make over 15 pounds of boost at 4000 RPM.

As far as the carburation, more turbos with carbs are about a 50-50 split between blow-through carbs and carbs in front of the turbo. I had a turbo on a 1200 Honda car that used a Harley Davidson sidedraft carb in front of the turbo. Ran real good, until I proved (twice!) that stock Honda rings couldn't take the heat and would lose all of their tension, leaving a huge smoke cloud when they died.

Did I mention that the race car I work on occasionally uses a Suzuki 1500 cc (90 ci) motorcycle engine running 25 pounds of boost and makes 350 HP on gasoline? It takes lots of expensive parts and a good fuel injection tuner, but it is fun!

Marty, thinking about the old days .......

That's true. Still prefer a procharger though.

In order to have the carb behind the turbo, it has to be able to take the pressure of the boost, or like studebaker incased in a housing that imerses the carb in the compressed charge so the pressure is equal inside and outside the carb. The only downfall of the suck through system is that both fuel and air are heated through the compression cycle which means that if not run through an inter cooler, means you are feeding the engine a less effective hot intake charge rather than the preferabel denser cooler charge of a non compressed normally aspirated charge. I believe the Corvair also used the suck through side draft style system. The preference for port injection is that the fuel is introduced in the previously compressed air.

Hm, interesting. I'll keep all this in mind, though as I stated, I'm still more of a fan of the forced induction of a blower. Turbo has too much lag, and I'm not too fond of the exhaust being the basis of it's power.

[greg g]

Other than a bit of lag, turbo is basically free of HP loss. Lag can be minimized by using small compressors. This limits boos but boost begins at lower RPM. My experience with a Volvo Turbo charged wagon was quite positve. I woudl suggest anyone contemplating going the turbo route using these a s a source for parts and pieces. Lots of turbo Volvos moldering about in bone yards. Mine was a 2.4 liter. I believe the yield was 170 hp, a gain of 65 over the atmospheric version. Lag was minimal. Got good mileage on the highway, was a hoot running through the gears.

[Don Coatney]

I believe Kiser also used the boxed carburetor version. No way would a B&B work with forced induction unless it were boxed.

[martybose]

Don't forget that with a boxed carburetor you also have to have a way to raise the fuel pressure with boost, or you can either wind up with not enough fuel volume or no fuel at all.

Hm, interesting, thanks, Greg, I'll have to keep that in mind.
